Methods and systems for providing multi-source content in electronic program guides

One or more computer-readable media having computer-readable instructions thereon which, when executed, implement a method comprising:

• accessing a list of all lineups available on one or more inputs of one or more tuners;
• removing any duplicate lineups;
• sorting channels of the lineups based on the channel number and retaining occurrences of the same channel number from different sources;
• for any channels with the same channel number, sorting the same channel numbers as a function of the source associated with the channel number effective to provide a merged lineup, wherein the act of sorting the same channel number comprises arranging the same channel numbers in the following source order:
• cable, antenna and satellite;
• presenting an electronic program guide that embodies the merged lineup;
• receiving a viewer channel selection independent of presentation of the electronic program guide associated with the merged lineup and responsive to receiving the channel selection, performing one or more of the following:
• attempting to tune to the channel using a predefined tuning source order as follows:
• analog cable source, digital cable source, antenna source and satellite source;
• in an event the viewer channel selection is a channel up, attempting to tune to the next higher channel with a different service;
• or
• in an event the viewer channel selection is a channel down, attempting to tune to the next lower channel with a different service.
